Abstract

A 3-mode fiber with pure silica core and dual-step index profile is numerically investigated for realizing low DMD and low loss. We found a structure that minimizes DMD while maintaining the low loss property of the pure silica core. We also show that lower loss and larger MFD properties are restricted by the requirement for the micro-bending sensitivity.
